LeBron James Polymarket Deal Worth $15 Million a Year

LeBron James will earn more from his Polymarket collaboration than his salary with the Philadelphia 76ers, according to Front Office Sports. The prediction-market platform is paying James an annual sum of $15 million, which is disclosed by sources. James is not an investor in Polymarket; he only endorses the brand. The duration of his agreement with Polymarket is unclear, but it is described as an ongoing engagement with various deliverables, such as social media posts and other content.

James will primarily promote football through this partnership, not basketball. Other prominent athletes, including Derek Jeter and Eli Manning, are paid significantly less than James for their appearances in Polymarket commercials. The commercial also featured celebrities like Spike Lee, Reggie Bush, and Alexandra Daddario, some of whom received only one-time payments for the ad.

James signed a two-year, $8 million contract with the 76ers in July, which will pay him less than one-third of what Polymarket is paying him annually for the 2026–27 season. Prediction-market platforms have been competing for attention and customers since the start of the football season, with Kalshi recently featuring former NFL running back Marshawn Lynch and several NBA players as investors.

Both Polymarket and Kalshi are official partners of the NHL, while Polymarket is MLB's exclusive prediction-market partner and Kalshi is an authorized prediction market under MLB's integrity framework. The NBA and NFL have not embraced prediction markets, with the former reportedly close to agreements and the latter remaining firm in its stance.

The prediction-market industry, regulated at the federal level, has faced controversy and numerous lawsuits, with the issue of state regulation expected to reach the Supreme Court. Polymarket is backed by the parent of the New York Stock Exchange and Donald Trump Jr.'s investment firm, which recently injected an additional $1 billion into the business.
